LXT380 - Octal E1 G.703 Transceiver Note - Not recommended for new designs

 

The LXT380 is an octal short-haul Pulse Code Modulation (PCM) transceiver for use in 2.048 Mbps (E1) applications. It incorporates eight receivers and eight transmitters in a single 144-pin LQFP or 160 PBGA package. Controllable through either hardware or host mode (serial or parallel interface), the LXT380 exceeds the latest ETSI return loss recommendations. You can configure the LXT380 as a seven-channel transceiver for SDH tributary post cards with the additional channel configured as a G.772-compliant nonintrusive performance monitor. Cortina also offers "Hitless Protection Switching" (HPS), which incorporates fast tri-stateable drivers and a constant delay jitter attenuator. HPS helps you reduce system cost by eliminating costly mechanical relays and opto-isolators in 1+1 protection and redundancy applications. The switch over time from primary to backup board is less than 1us - more than 1,000 times faster than mechanical relays - and helps eliminate loss of frame synchronization. A maximum of 1 bit error is generated when HPS is used instead of relays, which can generate more than 6,000 bit errors. Analog and digital JTAG can also help reduce test costs by reducing test times. The LXT381 provides the same features, without support for nonintrusive performance monitoring or clock recovery.
